0 Posted May 10, 2013 What's the maximum product of any whole number of real numbers whose sum is 100? What are they? They should be the same numbers, so 100/n is the form and (100/n)^{n} is the solution. I get n = 37 Product = 9 474 061 716 781 820 Interestingly, n = 25 and n = 50 give the same product, namely 1 125 899 906 842 624. If n need not be integral, n =100/e gives 9 479 842 689 868 740 0 Share this post Link to post Share on other sites
